In addition to what I said in my last post, historically in Mormonism high ranking leaders starting with Joseph Smith and going down to Warren Jeffs (AKA Joseph Smith 2.0) have married other men's wives without their consent, going as far as sending them off on missions to other countries to keep them out of the way, marrying pairs of sisters, mother-daughter combinations and other really horrendous stuff. Mormonism is a really really really bad example of polygamy.
